In "1-axis linear control" (" Da. 2 Control method" = 1-axis linear control (ABS), 1-axis
linear control (INC), one motor is used to carry out position control in a set axis
direction.
[1] 1-axis linear control (ABS linear 1)
Operation chart
In absolute system 1-axis linear control, addresses established by a machine OPR
control are used. Position control is carried out from the current stop position (start
point address) to the address (end point address) set in " Da. 6 Positioning
address/movement amount".
Example
When the start point address (current stop position) is 1000, and the end point address (positioning address) is 8000,
position control is carried out in the positive direction for a movement amount of 7000 (8000-1000)
0 1000
